How Do You Calculate Mass from Weight on Different Planets?

[badboyben03]

If I am given the the weight of someone at 91 kg, and he's on a place that's (g=9.782m/s/s), i know to the weight (N), i multiply the 91kg and 9.782 m/s/s, but how do you find the mass of him in kg?

You only had to read it a second time? Usually I have to read a problem 3 or 4 times before it makes sense!

Can you read before you type?
